Digioh is a website that helps anybody to sell their own digital stuff, including documents, video, audio, photos. It has two plans: commercial and free. I only talk about free plan, 10 sales per month. You can offer price for your stuff, use your Paypal to accept bill. After you upload your stuff, it will give out download links, people use this link to buy your digital stuff. Only three simple steps. Pretty easy, right?
